## Features

A date field can be built using `<input type="date">`, but this is very limited in functionality, lacking in internationalization capabilities, inconsistent between browsers, and difficult to style. `DateField` helps achieve accessible and international date and time fields that can be styled as needed.

* **Dates and times** – Support for dates and times with configurable granularity.
* **International** – Support for 13 calendar systems used around the world, including Gregorian, Buddhist, Islamic, Persian, and more. Locale-specific formatting, number systems, hour cycles, and right-to-left support are available as well.
* **Time zone aware** – Dates and times can optionally include a time zone. All modifications follow time zone rules such as daylight saving time.
* **Accessible** – Each date and time unit is displayed as an individually focusable and editable segment, which allows users an easy way to edit dates using the keyboard, in any date format and locale.
* **Touch friendly** – Date segments are editable using an easy to use numeric keypad, and all interactions are accessible using touch-based screen readers.
* **Validation** – Integrates with HTML forms, supporting required, minimum and maximum values, custom validation functions, realtime validation, and server-side validation errors.
* **Customizable** – As with all of React Aria, the DOM structure and styling of all elements can be fully customized.

Read our [blog post](../blog/date-and-time-pickers-for-all.html) for more details about the internationalization, accessibility, and user experience features implemented by `DateField`.

## Anatomy

<Anatomy />

A date field consists of a label, and a group of segments representing each unit of a date and time (e.g. years, months, days, etc.). Each segment is individually focusable and editable by the user, by typing or using the arrow keys to increment and decrement the value. This approach allows values to be formatted and parsed correctly regardless of the locale or date format, and offers an easy and error-free way to edit dates using the keyboard.

`DateField` also supports optional description and error message elements, which can be used to provide more context about the field, and any validation messages. These are linked with the input via the `aria-describedby` attribute.

```tsx
import {DateField, Label, DateInput, DateSegment, Text, FieldError} from 'react-aria-components';

<DateField>
  <Label />
  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
  <Text slot="description" />
  <FieldError />
</DateField>
```

If the date field does not have a visible label, an `aria-label` or `aria-labelledby` prop must be passed instead to identify it to assistive technology.

Note that most of this anatomy is shared with [TimeField](TimeField.html), so you can reuse many components between them if you have both.

### Internationalization

To ensure the proper date and time format in RTL locales, `DateInput` must have `display` set to either `inline`, `inline-block`, or `block`. 

### Concepts

`DateField` makes use of the following concepts:

<section className={styles.cardGroup} data-size="small">

<ExampleCard
  url="../internationalized/date/index.html"
  title="@internationalized/date"
  description="Represent and manipulate dates and times in a locale-aware manner.">
  <InternationalizedDate />
</ExampleCard>

<ExampleCard
  url="forms.html"
  title="Forms"
  description="Validating and submitting form data, and integrating with form libraries.">
  <Form />
</ExampleCard>

</section>

### Composed components

A `DateField` uses the following components, which may also be used standalone or reused in other components.

<section className={styles.cardGroup} data-size="small">

<ExampleCard
  url="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/label"
  title="Label"
  description="A label provides context for an input element.">
  <Label />
</ExampleCard>

</section>

## Starter kits

To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured [Storybook](https://storybook.js.org/) that you can experiment with, or use as a starting point for your own component library.

<StarterKits component="datefield" />

## Reusable wrappers

If you will use a DateField in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps `DateField` and all of its children together into a single component which accepts a `label` prop, which is passed to the right place. It also shows how to use the `description` slot to render [help text](#description), and `FieldError` component to render [validation errors](#validation).

```tsx example export=true
import type {DateFieldProps, DateValue, ValidationResult} from 'react-aria-components';
import {Text, FieldError} from 'react-aria-components';

interface MyDateFieldProps<T extends DateValue> extends DateFieldProps<T> {
  label?: string,
  description?: string,
  errorMessage?: string | ((validation: ValidationResult) => string)
}

function MyDateField<T extends DateValue>({label, description, errorMessage, ...props}: MyDateFieldProps<T>) {
  return (
    <DateField {...props}>
      <Label>{label}</Label>
      <DateInput>
        {segment => <DateSegment segment={segment} />}
      </DateInput>
      {description && <Text slot="description">{description}</Text>}
      <FieldError>{errorMessage}</FieldError>
    </DateField>
  );
}

<MyDateField label="Event date" />
```

## Value

A `DateField` displays a placeholder by default. An initial, uncontrolled value can be provided to the `DateField` using the `defaultValue` prop. Alternatively, a controlled value can be provided using the `value` prop.

Date values are provided using objects in the [@internationalized/date](../internationalized/date/) package. This library handles correct international date manipulation across calendars, time zones, and other localization concerns. `DateField` supports values of the following types:

* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.CalendarDate} /> – a date without any time components. May be parsed from a string representation using the <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseDate} /> function. Use this type to represent dates where the time is not important, such as a birthday or an all day calendar event.
* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.CalendarDateTime} /> – a date with a time, but not in any specific time zone. May be parsed from a string representation using the <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseDateTime} /> function. Use this type to represent times that occur at the same local time regardless of the time zone, such as the time of New Years Eve fireworks which always occur at midnight. Most times are better stored as a `ZonedDateTime`.
* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.ZonedDateTime} /> – a date with a time in a specific time zone. May be parsed from a string representation using the <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseZonedDateTime} />, <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseAbsolute} />, or <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseAbsoluteToLocal} /> functions. Use this type to represent an exact moment in time at a particular location on Earth.

```tsx example
import {parseDate} from '@internationalized/date';

function Example() {
  let [value, setValue] = React.useState(parseDate('2020-02-03'));

  return (
    <>
      <MyDateField
        label="Date (uncontrolled)"
        defaultValue={parseDate('2020-02-03')} />
      <MyDateField
        label="Date (controlled)"
        value={value}
        onChange={setValue} />
    </>
  );
}
```

### Time zones

`DateField` is time zone aware when a <TypeLink links={i18nDocs.links} type={i18nDocs.exports.ZonedDateTime} /> object is provided as the value. In this case, the time zone abbreviation is displayed, and time zone concerns such as daylight saving time are taken into account when the value is manipulated.

In most cases, your data will come from and be sent to a server as an [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) formatted string. [@internationalized/date](../internationalized/date/) includes functions for parsing strings in multiple formats into <TypeLink links={i18nDocs.links} type={i18nDocs.exports.ZonedDateTime} /> objects. Which format you use will depend on what information you need to store.

* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseZonedDateTime} /> – This function parses a date with an explicit time zone and optional UTC offset attached (e.g. `"2021-11-07T00:45[America/Los_Angeles]"` or `"2021-11-07T00:45-07:00[America/Los_Angeles]"`). This format preserves the maximum amount of information. If the exact local time and time zone that a user selected is important, use this format. Storing the time zone and offset that was selected rather than converting to UTC ensures that the local time is correct regardless of daylight saving rule changes (e.g. if a locale abolishes DST). Examples where this applies include calendar events, reminders, and other times that occur in a particular location.
* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseAbsolute} /> – This function parses an absolute date and time that occurs at the same instant at all locations on Earth. It can be represented in UTC (e.g. `"2021-11-07T07:45:00Z"`), or stored with a particular offset (e.g. `"2021-11-07T07:45:00-07:00"`). A time zone identifier, e.g. `America/Los_Angeles`, must be passed, and the result will be converted into that time zone. Absolute times are the best way to represent events that occurred in the past, or future events where an exact time is needed, regardless of time zone.
* <TypeLink links={i18nDocs.links} type={i18nDocs.exports.parseAbsoluteToLocal} /> – This function parses an absolute date and time into the current user's local time zone. It is a shortcut for `parseAbsolute`, and accepts the same formats.

```tsx example
import {parseZonedDateTime} from '@internationalized/date';

<MyDateField
  label="Event date"
  defaultValue={parseZonedDateTime('2022-11-07T00:45[America/Los_Angeles]')} />
```

`DateField` displays times in the time zone included in the `ZonedDateTime` object. The above example is always displayed in Pacific Standard Time because the `America/Los_Angeles` time zone identifier is provided. [@internationalized/date](../internationalized/date/) includes functions for converting dates between time zones, or parsing a date directly into a specific time zone or the user's local time zone, as shown below.

```tsx example
import {parseAbsoluteToLocal} from '@internationalized/date';

<MyDateField
  label="Event date"
  defaultValue={parseAbsoluteToLocal('2021-11-07T07:45:00Z')}
/>
```

### Granularity

The `granularity` prop allows you to control the smallest unit that is displayed by `DateField`. By default, `CalendarDate` values are displayed with `"day"` granularity (year, month, and day), and `CalendarDateTime` and `ZonedDateTime` values are displayed with `"minute"` granularity. More granular time values can be displayed by setting the `granularity` prop to `"second"`.

In addition, when a value with a time is provided but you wish to only display the date, you can set the granularity to `"day"`. This has no effect on the actual value (it still has a time component), only on what fields are displayed. In the following example, two DateFields are synchronized with the same value, but display different granularities.

```tsx example
function Example() {
  let [date, setDate] = React.useState(parseAbsoluteToLocal('2021-04-07T18:45:22Z'));

  return (
    <>
      <MyDateField
        label="Date and time"
        /*- begin highlight -*/
        granularity="second"
        /*- end highlight -*/
        value={date}
        onChange={setDate} />
      <MyDateField
        label="Date"
        /*- begin highlight -*/
        granularity="day"
        /*- end highlight -*/
        value={date}
        onChange={setDate} />
    </>
  );
}
```


If no `value` or `defaultValue` prop is passed, then the `granularity` prop also affects which type of value is emitted from the `onChange` event. Note that by default, time values will not have a time zone because none was supplied. You can override this by setting the `placeholderValue` prop explicitly. Values emitted from `onChange` will use the time zone of the placeholder value.

```tsx example
import {now} from '@internationalized/date';

<MyDateField
  label="Event date"
  granularity="second" />
<MyDateField
  label="Event date"
  placeholderValue={now('America/New_York')}
  granularity="second" />
```

### International calendars

`DateField` supports selecting dates in many calendar systems used around the world, including Gregorian, Hebrew, Indian, Islamic, Buddhist, and more. Dates are automatically displayed in the appropriate calendar system for the user's locale. The calendar system can be overridden using the [Unicode calendar locale extension](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Locale/calendar#adding_a_calendar_in_the_locale_string), passed to the [I18nProvider](I18nProvider.html) component.

Selected dates passed to `onChange` always use the same calendar system as the `value` or `defaultValue` prop. If no `value` or `defaultValue` is provided, then dates passed to `onChange` are always in the Gregorian calendar since this is the most commonly used. This means that even though the user selects dates in their local calendar system, applications are able to deal with dates from all users consistently.

The below example displays a `DateField` in the Hindi language, using the Indian calendar. Dates emitted from `onChange` are in the Gregorian calendar.

```tsx example
import {I18nProvider} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState<DateValue | null>(null);
  return (
    /*- begin highlight -*/
    <I18nProvider locale="hi-IN-u-ca-indian">
    {/*- end highlight -*/}
      <MyDateField label="Date" value={date} onChange={setDate} />
      <p>Selected date: {date?.toString()}</p>
    </I18nProvider>
  );
}
```

### HTML forms

DateField supports the `name` prop for integration with HTML forms. The value will be submitted to the server as an [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) formatted string according to the granularity of the value. For example, if the date field allows selecting only a date then a string such as `"2023-02-03"` will be submitted, and if it allows selecting a time then a string such as `"2023-02-03T08:45:00"` will be submitted. See the [Value](#value) section above for more details about the supported value types.

```tsx example
<MyDateField label="Birth date" name="birthday" />
```

## Events

`DateField` accepts an `onChange` prop which is triggered whenever the date is edited by the user. The example below uses `onChange` to update a separate element with a formatted version of the date in the user's locale and local time zone. This is done by converting the date to a native JavaScript `Date` object to pass to the formatter.

```tsx example
import {getLocalTimeZone} from '@internationalized/date';
import {useDateFormatter} from '@react-aria/i18n';

function Example() {
  let [date, setDate] = React.useState(parseDate('1985-07-03'));
  let formatter = useDateFormatter({dateStyle: 'full'});

  return (
    <>
      <MyDateField label="Birth date" value={date} onChange={setDate} />
      <p>Selected date: {date ? formatter.format(date.toDate(getLocalTimeZone())) : '--'}</p>
    </>
  );
}
```

## Validation

DateField supports the `isRequired` prop to ensure the user enters a value, as well as minimum and maximum values, and custom client and server-side validation. It can also be integrated with other form libraries. See the [Forms](forms.html) guide to learn more.

To display validation errors, add a `<FieldError>` element as a child of the DateField. This allows you to render error messages from all of the above sources with consistent custom styles.

```tsx example
import {Form, FieldError, Button} from 'react-aria-components';

<Form>
  {/*- begin highlight -*/}
  <DateField name="date" isRequired>
  {/*- end highlight -*/}
    <Label>Appointment date</Label>
    <DateInput>
      {segment => <DateSegment segment={segment} />}
    </DateInput>
    {/*- begin highlight -*/}
    <FieldError />
    {/*- end highlight -*/}
  </DateField>
  <Button type="submit">Submit</Button>
</Form>
```

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show CSS</summary>

```css
.react-aria-DateSegment {
  &[data-invalid] {
    color: var(--invalid-color);

    &:focus {
      background: var(--highlight-background-invalid);
      color: var(--highlight-foreground);
    }
  }
}

.react-aria-DateField {
  .react-aria-FieldError {
    font-size: 12px;
    color: var(--invalid-color);
  }
}
```

</details>

By default, `FieldError` displays default validation messages provided by the browser. See [Customizing error messages](forms.html#customizing-error-messages) in the Forms guide to learn how to provide your own custom errors.

### Minimum and maximum values

The `minValue` and `maxValue` props can also be used to ensure the value is within a specific range. This example only accepts dates after today.

```tsx example
import {today} from '@internationalized/date';

<Form>
  <MyDateField
    label="Appointment date"
    /*- begin highlight -*/
    minValue={today(getLocalTimeZone())}
    /*- end highlight -*/
    defaultValue={parseDate('2022-02-03')} />
  <Button type="submit">Submit</Button>
</Form>
```

### Custom validation

The `validate` function can be used to perform custom validation logic. It receives the current field value, and should return a string or array of strings representing one or more error messages if the value is invalid.

This example validates that the selected date is a weekday and not a weekend according to the current locale.

```tsx example
import {isWeekend} from '@internationalized/date';
import {useLocale} from 'react-aria';

function Example() {
  let {locale} = useLocale();

  return (
    <Form>
      <MyDateField
        label="Appointment date"
        /*- begin highlight -*/
        validate={date => date && isWeekend(date, locale) ? 'We are closed on weekends.' : null}
        /*- end highlight -*/
        defaultValue={parseDate('2023-10-28')} />
      <Button type="submit">Submit</Button>
    </Form>
  );
}
```

### Description

The `description` slot can be used to associate additional help text with a date field.

```tsx example
<DateField granularity="hour">
  <Label>Appointment time</Label>
  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
  {/*- begin highlight -*/}
  <Text slot="description">Please select a weekday between 9 AM and 5 PM.</Text>
  {/*- end highlight -*/}
</DateField>
```

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show CSS</summary>

```css
.react-aria-DateField {
  [slot=description] {
    font-size: 12px;
  }
}
```

</details>

## Format options

### Placeholder value

When no value is set, a placeholder is shown. The format of the placeholder is influenced by the `granularity` and `placeholderValue` props. `placeholderValue` also controls the default values of each segment when the user first interacts with them, e.g. using the up and down arrow keys. By default, the `placeholderValue` is the current date at midnight, but you can set it to a more appropriate value if needed.

```tsx example
import {CalendarDate} from '@internationalized/date';

<MyDateField
  label="Birth date"
  placeholderValue={new CalendarDate(1980, 1, 1)} />
```

### Hide time zone

When a `ZonedDateTime` object is provided as the value to `DateField`, the time zone abbreviation is displayed by default. However, if this is displayed elsewhere or implicit based on the usecase, it can be hidden using the `hideTimeZone` option.

```tsx example
<MyDateField
  label="Appointment time"
  defaultValue={parseZonedDateTime('2022-11-07T10:45[America/Los_Angeles]')}
  hideTimeZone />
```

### Hour cycle

By default, `DateField` displays times in either 12 or 24 hour hour format depending on the user's locale. However, this can be overridden using the `hourCycle` prop if needed for a specific usecase. This example forces `DateField` to use 24-hour time, regardless of the locale.

```tsx example
<MyDateField
  label="Appointment time"
  granularity="minute"
  hourCycle={24} />
```

## Props

### DateField

<PropTable component={docs.exports.DateField} links={docs.links} />

### Label

A `<Label>` accepts all HTML attributes.

### DateInput

The `<DateInput>` component renders a group of date segments. It accepts a function as its `children`, which is called to render a `<DateSegment>` for each segment.

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show props</summary>

<PropTable component={docs.exports.DateInput} links={docs.links} />

</details>

### DateSegment

The `<DateSegment>` component renders an individual segment.

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show props</summary>

<PropTable component={docs.exports.DateSegment} links={docs.links} />

</details>

### FieldError

A `<FieldError>` displays validation errors.

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show props</summary>

<PropTable component={docs.exports.FieldError} links={docs.links} />

</details>

## Styling

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin `className` attribute which can be targeted using CSS selectors. These follow the `react-aria-ComponentName` naming convention.

```css
.react-aria-DateField {
  /* ... */
}
```

A custom `className` can also be specified on any component. This overrides the default `className` provided by React Aria with your own.

```jsx
<DateInput className="my-date-input">
  {/* ... */}
</DateInput>
```

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:

```css
.react-aria-DateSegment[data-placeholder] {
  /* ... */
}

.react-aria-DateSegment[data-readonly] {
  /* ... */
}
```

The `className` and `style` props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like [Tailwind](https://tailwindcss.com/).

```jsx
<DateSegment className={({isPlaceholder}) => isPlaceholder ? 'bg-gray-300' : 'bg-gray-600'} />
```

Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render the placeholder as a separate element to always reserve space for it.

```jsx
<DateSegment>
  {({text, placeholder, isPlaceholder}) => (
    <>
      <span style={{visibility: isPlaceholder ? 'visible' : 'hidden'}}>{placeholder}</span>
      {isPlaceholder ? '' : text}
    </>
  )}
</DateSegment>
```

The states, selectors, and render props for each component used in a `DateField` are documented below.

### DateField

A `DateField` can be targeted with the `.react-aria-DateField` CSS selector, or by overriding with a custom `className`. It supports the following states and render props:

<StateTable properties={docs.exports.DateFieldRenderProps.properties} />

### Label

A `Label` can be targeted with the `.react-aria-Label` CSS selector, or by overriding with a custom `className`.

### DateInput

A `DateInput` can be targeted with the `.react-aria-DateInput` CSS selector, or by overriding with a custom `className`. It supports the following states:

<StateTable properties={docs.exports.DateInputRenderProps.properties} />

### DateSegment

A `DateSegment` can be targeted with the `.react-aria-DateSegment` CSS selector, or by overriding with a custom `className`. It supports the following states and render props:

<StateTable properties={docs.exports.DateSegmentRenderProps.properties} />

### Text

The help text elements within a `DateField` can be targeted with the `[slot=description]` and `[slot=errorMessage]` CSS selectors, or by adding a custom `className`.

### FieldError

A `FieldError` can be targeted with the `.react-aria-FieldError` CSS selector, or by overriding with a custom `className`. It supports the following render props:

<StateTable properties={docs.exports.FieldErrorRenderProps.properties} />

## Advanced customization

### Composition

If you need to customize one of the components within a `DateField`, such as `Label` or `DateSegment`, in many cases you can create a wrapper component. This lets you customize the props passed to the component.

```tsx
function MyDateSegment(props) {
  return <MyDateSegment {...props} className="my-date-segment" />
}
```

### Contexts

All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in [mergeProps](mergeProps.html)).

The components in a DateField support the following contexts:

<ContextTable components={['DateField']} docs={docs} />

This example shows a `FieldGroup` component that renders a group of date fields with a title and optional error message. It uses the [useId](useId.html) hook to generate a unique id for the error message. All of the child DateFields are marked invalid and associated with the error message via the `aria-describedby` attribute passed to the `DateFieldContext` provider.

```tsx example
import {DateFieldContext} from 'react-aria-components';
import {useId} from 'react-aria';

interface FieldGroupProps {
  title?: string,
  children?: React.ReactNode,
  errorMessage?: string
}

function FieldGroup({title, children, errorMessage}: FieldGroupProps) {
  let errorId = useId();
  return (
    <fieldset>
      <legend>{title}</legend>
      {/*- begin highlight -*/}
      <DateFieldContext.Provider value={{
        isInvalid: !!errorMessage,
        'aria-describedby': errorMessage ? errorId : undefined
      }}>
      {/*- end highlight -*/}
        {children}
      </DateFieldContext.Provider>
      {errorMessage && <small id={errorId} className="invalid">{errorMessage}</small>}
    </fieldset>
  );
}

<FieldGroup title="Dates" errorMessage="Tickets must go on sale before event.">
  <MyDateField label="Event date" defaultValue={parseDate('2023-07-12')} />
  <MyDateField label="Ticket sale date" defaultValue={parseDate('2023-08-03')} />
</FieldGroup>
```

<details>
  <summary style={{fontWeight: 'bold'}}><ChevronRight size="S" /> Show CSS</summary>

```css
fieldset {
  padding: 1.5em;
  width: fit-content;
}

.invalid {
  color: var(--invalid-color);
  margin-top: 1em;
  display: block;
}
```

</details>

### Custom children

DateField passes props to its child components, such as the label, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.

<ContextTable components={['Label', 'Text']} docs={docs} />

This example consumes from `LabelContext` in an existing styled label component to make it compatible with React Aria Components. The <TypeLink links={docs.links} type={docs.exports.useContextProps} /> hook merges the local props and ref with the ones provided via context by DateField.

```tsx
import type {LabelProps} from 'react-aria-components';
import {LabelContext, useContextProps} from 'react-aria-components';

const MyCustomLabel = React.forwardRef((props: LabelProps, ref: React.ForwardedRef<HTMLLabelElement>) => {
  // Merge the local props and ref with the ones provided via context.
  ///- begin highlight -///
  [props, ref] = useContextProps(props, ref, LabelContext);
  ///- end highlight -///

  // ... your existing Label component
  return <label {...props} ref={ref} />;
});
```

Now you can use `MyCustomLabel` within a `DateField`, in place of the builtin React Aria Components `Label`.

```tsx
<DateField>
  {/*- begin highlight -*/}
  <MyCustomLabel>Name</MyCustomLabel>
  {/*- end highlight -*/}
  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
</DateField>
```

### State

DateField provides a <TypeLink links={statelyDocs.links} type={statelyDocs.exports.DateFieldState} /> object to its children via `DateFieldStateContext`. This can be used to access and manipulate the date field's state.

This example shows a `DateFormat` component that can be placed within a `DateField` to display the expected date format.

```tsx example
import {DateFieldStateContext} from 'react-aria-components';
import {useLocale} from 'react-aria';

function DateFormat() {
  /*- begin highlight -*/
  let state = React.useContext(DateFieldStateContext)!;
  /*- end highlight -*/
  let {locale} = useLocale();
  let displayNames = new Intl.DisplayNames(locale, {type: 'dateTimeField'});
  let format = state.segments.map(segment => segment.type === 'literal' ? segment.text : displayNames.of(segment.type)).join(' ');
  return <small>{format}</small>;
}

<DateField defaultValue={today(getLocalTimeZone())}>
  <Label>Date</Label>
  <DateInput>
    {segment => <DateSegment segment={segment} />}
  </DateInput>
  {/*- begin highlight -*/}
  <DateFormat />
  {/*- end highlight -*/}
</DateField>
```

### Hooks

If you need to customize things even further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. See [useDateField](useDateField.html) for more details.
